The craziest suspension ever!

[dude772]

Found this while looking for different suspension designs.

Man that is pretty cool, the coolest part is when it does the nightrider jump over the curb! So when do you think they'll make a longtravel kit? lol

[BDAB]

lol that is crazy ..... MAKG would like this one.

[dangeranger01]

That was awsome!!!!!!!!!

[Wicked_Sludge]

haha, i totally didnt see that coming :clapping:

you know that really opens up a lot of options for vehicle suspensions though. being able to actively adjust for loads and conditions means you could have an f-350 that rides like a crown vic both empty or while towing 12,000lbs.

think of the amperage that thing would use. it might need a 2000 amp alternator.

Not really. The optimal algorithm -- if done correctly -- would be the one that uses the smallest average current. It's mathematically equivalent to how much jarring the driver feels.

It sounds like a clever idea -- and these guys have rep for clever ideas -- but it's rather hard to evaluate when the algorithms are "proprietary." That's what patents are for (yes, you CAN patent an algorithm, and there have been several well known examples, such as RSA encryption).

Don't think of these like "hydraulics" like you might see in a Cheech & Chong movie. That's not how you would want to operate it.

While this approach sounds very interesting, the one I **REALLY** want to see is electromagnetic engine valves. If you could control those with a module, you could dynamically adjust valve timing, duration, lift, and so on adaptively for conditions, and make a "perfect" engine without a bunch of camshafts, chains, etc.

the article said it uses about 1/3 of the energy needed to run the A/C system.

[JFA_Spyderman]

Yo,
That is pretty sick. There has got to be some way to adapt that to 4x4ing.

I wish they would get really up close and show you how the suspension system works. Did anybody see a link for the english version?

Amen to that!!! It would open up a whole new avenue to tuning of the average car......and with presets, max economy day to day and almost a top fueler on the weekend.....with reduced valvetrain load on the engine to boot!!

dude , thats awsome

Already been done, in fact Ford has the technology and has test mules using it.

i thought that sounded familiar. hasnt honda done some similer experiments?

[arrabil]

and these guys have rep for clever ideas
Name some please.

I see 4, 2 direction linear motors possably that are computer controled with regererating capability.
on smooth flat road I could believe their power estimates but no way on the illmaintained streets in many US cities, or offroading.

To name some the 321 sytstem is amazing, and bose system is amazing

[dude772]

I couldn't find an english version of the video, but on the bose sight where i posted the tech on it they have more videos of it, but they dont have the curb jump video.

[Wicked_Sludge]

those noise canceling headphones the guy in the youtube clip puts on are pretty cool too. they weigh next to nothing, but deaden external noise just as well (or better) as normal, bulky hearing protection. plus they double as headphones :icon_thumby:

First user of it that I know of was McLaren. Probably everyone has at leat 1 test mule using it now. Through a friend of my old boss I got to meet the Russia guys who developed the process to make the ultra-light weight linear servos that drove the valves. A full cycle, closed to max open to close, could be done in milliseconds. Lift and duration were completely controlled by the computer.

[JFA_Spyderman]

Yo,
I could be wrong, but it looked like the car actually jumped the curb, it never touched it. Do you think the sensors were controlling that? Or was it the driver? The reason i ask is because at the end of the video, the car bows with the driver. So someone has control.

[AgPete139]

Wow...never seen before, and am currently reading more on this...
